2016 F250 tranny

My only issue with the new slush boxes and all that 'shifting' is heat. When the clutch packs unlock and relock, heat is produced with every change. Slushboxes don't like heat no matter what year they are.
heat kills slush boxes, always has.
With the new improved cooling on the trucks I've had I see no tranny heat issues. On my 2010 F150 6 sp it had no OD lockout and no way to choose gears. Put it in drive and you take what it gives. It shifted back and forth all the time. Used a scan gauge and temps never hardly moved except when climbing steeper grades in hot weather.
Both My 2012 Ram CTD and my 2018 Ram 6.4 pretty much stay in the 168-170 range until the same scenario as above.
Now my 08 F150 5.4 3.73 4 sp got lots of heat spikes. It just didn't have the better tranny cooling that newer trucks have.
